PEL: Use new Compatible interface

Code previously looked at an IBMCompatible interface provided by
entity-manager to get the system type in order to find the device
callouts file when necessary.

EM now also puts the xyz.openbmc_project.Inventory.Decorator.Compatible
on D-Bus with the same Names property.

Change the code to use this new interface so it isn't using an IBM
specific one.

Tested:
With the dev_callouts file renamed in /usr/share:
```
/usr/share/phosphor-logging/pels# ls *Rainier2U*
com.ibm.Hardware.Chassis.Model.Rainier2U_dev_callouts.json
```

and with entity-manager hosting the new interface:

```
busctl get-property xyz.openbmc_project.EntityManager
/xyz/openbmc_project/inventory/system/chassis/Rainier_2U_Chassis \
xyz.openbmc_project.Inventory.Decorator.Compatible Names \
as 2
"com.ibm.Hardware.Chassis.Model.Rainier2U"
"com.ibm.Hardware.Chassis.Model.Rainier"
```

Creating a PEL with a device path callout:
```
CALLOUT_DEVICE_PATH /sys/bus/i2c/devices/7-0052
```

Leads to PEL callouts of:
```
    "Callout Section": {
        "Callout Count":        "3",
        "Callouts": [{
            "FRU Type":         "Normal Hardware FRU",
            "Priority":         "Mandatory, replace all with this type as a unit",
            "Location Code":    "U78DA.ND0.1234567-P0-C5",
            "Part Number":      "F191014",
            "CCIN":             "6B58",
            "Serial Number":    "YL6B58010000"
        }, {
            "FRU Type":         "Normal Hardware FRU",
            "Priority":         "Mandatory, replace all with this type as a unit",
            "Location Code":    "U78DA.ND0.1234567-P0-T10",
            "Part Number":      "F191014",
            "CCIN":             "2E2D",
            "Serial Number":    "YL2E2D010000"
        }, {
            "FRU Type":         "Normal Hardware FRU",
            "Priority":         "Lowest priority replacement",
            "Location Code":    "U78DA.ND0.1234567-P0",
            "Part Number":      "F191014",
            "CCIN":             "2E2D",
            "Serial Number":    "YL2E2D010000"
        }]
    }
```

which matches what's in the file.
